title: The problem of conflicting reference frames when investigating three-dimensional space in surface-dwelling animals.
abstract: In a surface-dwelling animal like the rat, experimental strategies for investigating the hippocampal correlates of three-dimensional space appear inevitably complicated by the interplay of global versus local reference frames. We discuss the impact of the resulting confounds on present and future empirical analysis of the "bicoded map" hypothesis by Jeffery and colleagues.
